8c84f3581a Attempted to bring some uniformity in application of configurations. 2016-09-08 05:32:17 -04:00
Thomas Harte
21e5f407d8 I need to get a bit more definitive on naming but this gets all the way to setting a configuration upon an Electron. 2016-08-31 22:03:42 -04:00
Thomas Harte
c0402d0c2b Gave tapes their own namespace. 2016-08-27 17:09:45 -04:00
Thomas Harte
d9016909ed Added some wiring for PAL/NTSC mode switching on the Vic, making an attempt to simplify the whole loop of having different clock rates. 2016-08-14 13:33:20 -04:00
Thomas Harte
5d40d70c92 Fixed 6560 addressing error, added an autotyper for Vic disks (more work potentially needed), fixed semantics for testing whether a 6502 is about to reset. 2016-08-01 10:32:32 -04:00
Thomas Harte
2332f72875 Formalised clock-rate multiplication within disk drives, discovered that the stepper didn't have ideal behaviour for my timed event loop and hence nailed down the semantics a ilttle more.
(obiter: the 1540 now appears to discern the correct sequence of bits. Framing is off in my test printfs but that's neither here nor there).

88964ceac0 Eliminated plain pointer passing for object types. 2016-07-04 19:33:55 -04:00
Thomas Harte
0182b0483a Added a 'power on' flag that is set automatically at construction but can be declined. Saves all that stuff of every machine having to set and then unset the RST line, and fixes an Electron bug related to that. 2016-06-29 19:13:24 -04:00
Thomas Harte
37ba42a52f Factored out the stuff of playing a tape, started basic sketch of the Vic-related classes. 2016-06-26 19:03:57 -04:00
Thomas Harte
2bd71e7e9b .reset is the more normal way to reassign a unique_ptr. 2016-06-23 20:52:44 -04:00
Thomas Harte
b6dd38dad3 Corrected type safety warning. 2016-06-19 21:41:01 -04:00
Thomas Harte
6dd8ea67c9 Tested and trimmed delay on typing if resetting. 2016-06-19 17:27:23 -04:00
Thomas Harte
05cb47709e Implemented Utility::Typer for the Electron. So that now also receives pastes. 2016-06-19 17:25:35 -04:00
Thomas Harte
00a9f1bf24 Fixed best-effort updater actually to run, finally moved clock rate announcement into the C++ side of things, started working on a mechanism to allow clock rate to be updated. 2016-06-16 20:39:46 -04:00
Thomas Harte
8dc66167be Made an attempt to consolidate the Objective-C++ side of things based on the incoming CRTMachine::Machine. 2016-05-31 22:16:20 -04:00
Thomas Harte
5c4f35e13f Finally started on generalising the C++ stuff so as to be able to be able to get a working audio binding on the OS-specific side without further repetition by factoring an appropriate protocol out from the Electron and sketching out the correct speaker class for the Atari. Added a method to ask it what a good output frequency would be. 2016-05-31 21:23:44 -04:00
Thomas Harte
5a4262d74e Confirmed: it is inaccurate for a 6502 to self reset at power up. So that responsibility now rests in the machines. 2016-05-10 21:05:52 -04:00
Thomas Harte
bf9917707e Merge branch 'master' into Glitches 2016-05-05 08:31:40 -04:00
Thomas Harte
fea32869b0 Implemented what I now believe to be the real paging logic. 2016-05-05 08:28:06 -04:00
Thomas Harte
87df57195d Started on an attempt not to treat the various buffers as free to loop within, starting with the input texture. 2016-05-04 07:39:45 -04:00
Thomas Harte
9b64f64db7 Attempted to normalise some style decisions.` 2016-04-24 22:32:24 -04:00
Thomas Harte
d221c712b0 Ensured GL context is active when destructing CRTOpenGL. 2016-04-24 20:34:25 -04:00
Thomas Harte
ae2760e034 Colour phase is now updated and varies per line. 2016-04-21 21:07:29 -04:00
Thomas Harte
7aa87723a9 Added: key states are all cleared if the window loses focus. Which resolves sticky key issues. Allowing me just to use command+option+O for options and map both command and option as FUNC. 2016-04-19 21:29:10 -04:00
Thomas Harte
66f2c10c04 Resolved potential crash if tape requests are made without one inserted. Softened glFinish to glFlush, though I'm still not sure I should strictly need even that. 2016-04-19 21:00:48 -04:00
Thomas Harte
3d53f157de Output selection now takes effect. So I can stop accidentally committing changes back and forth. 2016-04-18 08:27:58 -04:00
Thomas Harte
94f148e212 Wired in options, at least getting as far as the Objective-C bridge. Then fast loading makes it to the emulated machine, display output type doesn't. 2016-04-18 08:21:00 -04:00
Thomas Harte
499f7ace07 Re-enabled working video output for the Electron for the day and consolidated the rough metric I'm using to pick a number of taps for the audio filter. 2016-04-17 20:43:20 -04:00
Thomas Harte
6ff9ffba6c Switching temporarily to an attempt to draw input runs as if RGB: shader compiles, fixed a race condition on out-of-bounds accesses for the source buffer. 2016-04-17 15:51:28 -04:00
Thomas Harte
104f44f27f Attempted to improve deinterlacing, gave the CRT full control over blend mode, switched back to 2000000Mhz audio. 2016-04-14 22:20:47 -04:00
Thomas Harte
6a17c2992d Introduced a compile-time configurable audio divider, set it arbitrarily to '8' for now. Discovered why my graphics aren't centred and added a TODO. 2016-04-13 22:31:59 -04:00
Thomas Harte
026ce0255f Source runs are now captured, and that buffer appropriately reset. 2016-04-13 22:20:13 -04:00
Thomas Harte
2ea02ed127 A source array buffer is also now created, mapped, unmapped, etc. 2016-04-13 22:14:18 -04:00
Thomas Harte
955e185790 Minor simplification. 2016-04-13 19:19:04 -04:00
Thomas Harte
4d889d9c7f Made an attempt slightly to simplify the fragment processor, at both ends. 2016-04-12 22:35:11 -04:00
Thomas Harte
2cc72169ff Ensured machines can nominate their own aspect ratio windows. Switched to 11/10 for the Electron. 2016-04-11 23:12:56 -04:00
Thomas Harte
7276a06cc0 Added a helper to calculate a visible rect based on output timings, used it to scale the Electron output up to the full window size. 2016-04-11 21:47:23 -04:00
Thomas Harte
a3c2cd880e I discovered a further post on this on the STH forums; apparently the Electron simply asserts sync continuously. No breaks. 2016-04-11 21:01:09 -04:00
Thomas Harte
bdb99ba92f Corrections back towards composite output: fixed misnamed constant, ensured the CRT doesn't write nonsense to the output buffer, ensured it grows three vertices at a time rather than six when desired. Net effect should be that the output stage is working again, with the input processing remaining to fill in. 2016-04-10 22:56:52 -04:00
Thomas Harte
8701366277 Switched horizontal sync detection back to differential, switched the Electron to an XOR-style sync output (believed to be accurate, but I need to check), fixed some latent issues around vertical sync detection. 2016-04-10 21:34:40 -04:00
Thomas Harte
e617bd2bb3 Turned audio quality up to the maximum, at least for now. 2016-04-06 21:12:22 -04:00
Thomas Harte
5aa6da221f Shifted responsibility for byte shifts, probably to a more logical place. 2016-04-05 22:19:14 -04:00
Thomas Harte
2248769df9 Pulled a bunch of selection parts outside of the loops. Probably exhausting this angle of attack. 2016-04-05 22:17:44 -04:00
Thomas Harte
8f87973a96 Switched to table-based byte to output conversion. 2016-04-05 22:07:10 -04:00
Thomas Harte
e35456612a Simplified 40-column to pixel conversion. 2016-04-05 20:44:05 -04:00
Thomas Harte
6dbd20ffde Expanded interface to rgb_sample to eliminate its need to make assumptions about globals, used expanded interface to compact Electron data to two pixels per byte. 2016-04-05 20:32:55 -04:00
Thomas Harte
7838507a7a Simplified sound generation. 2016-04-04 22:22:19 -04:00
Thomas Harte
729fddea1c Switched to integer textures, likely to simplify for most use cases. 2016-04-04 19:39:01 -04:00
Thomas Harte
3ca58b2a57 Attemted further to diminish jumpiness. 2016-03-22 22:07:30 -04:00
Thomas Harte
8cd5d40e00 Made an attempt to reduce the amount of data heading to the GPU. 2016-03-22 21:16:32 -04:00
Thomas Harte
902017a962 Fixes: drop any processing backlog, try not to allow an Electron document to close mid-draw, perform a frame grab even if the emulated machine is over-processing, really really don't create a CRT until it's safe. 2016-03-20 18:42:37 -04:00
Thomas Harte
fb6fb5d948 Switched to two-phase setup to deal with OpenGL scheduling. 2016-03-20 13:50:13 -04:00
Thomas Harte
aa8a192c7e Simplified API down to their being a single texture with a specified depth. 2016-03-19 17:37:55 -04:00
Thomas Harte
b074860031 Updated to latest information on interrupt timing. 2016-03-18 21:11:25 -04:00
Thomas Harte
4cd0aa3416 Completed FIR filter based audio output. 2016-03-15 23:37:35 -04:00
Thomas Harte
0edf165401 Fixed sound pitch, though I'm not yet exactly sure why. 2016-03-14 22:52:16 -04:00
Thomas Harte
9a492ac15f Made a further guess at the state interrupts would probably be left; slightly simplified interface. 2016-03-14 22:42:52 -04:00
Thomas Harte
15120d8fb6 Switched to probably more accurate contended memory, resolved issue of not leaving the tape data received interrupt set when returning a byte from the fast tape, fixing Joe Blade, and tested slightly further to determine that interrupts probably signal upon entry into horizontal sync. 2016-03-14 19:29:28 -04:00
Thomas Harte
fb26b38ff9 This is as simplified as things seem to be able to get without breaking at least Northern Star. Joe Blade et al remain stubbornly broken but I'm not immediately able to determine why. 2016-03-13 19:55:20 -04:00
Thomas Harte
f797e6b5b6 Started taking baby steps towards a genuine unification of the tape interrupt generating code. 2016-03-13 19:45:50 -04:00
Thomas Harte
bc554dedf7 Fixed: attempting to read the screen start address no longer alters it. 2016-03-13 18:50:23 -04:00
Thomas Harte
1c4acfb599 I think this is a prima facie acceptable implementation of the fast tape hack. 2016-03-13 17:39:53 -04:00
Thomas Harte
4462bb92f8 Moved interrupt back down to where it's probably meant to be. 2016-03-12 23:18:46 -05:00
Thomas Harte
cdff90f20d Fixed: setting an interrupt control value with the lowest bit set could result in interrupts that can't be disabled. 2016-03-12 22:55:33 -05:00
Thomas Harte
6327311130 Made an attempt to separate and clarify on tape interrupts. 2016-03-12 20:32:26 -05:00
Thomas Harte
cfa616d593 Fixed: timing issue versus supplied test ROM was failure to include the Plus 1 ROM in the mix. 2016-03-12 11:51:20 -05:00
Thomas Harte
763d5e8819 Access timing now appears to be exactly on the nail. Disabled automatic interrupt expiration again as I'm not persuaded it's correct for at least the RTC. 2016-03-10 23:12:28 -05:00
Thomas Harte
e305fd9326 Adjusted numbers, empirically. 2016-03-10 22:40:18 -05:00
Thomas Harte
a89225987f Blank lines are back. 2016-03-10 22:19:54 -05:00
Thomas Harte
b836d74e18 Believing the previous implementation to be overly complicated through premature optimisation, simplified video. It's slightly slower now. Will need work. Immediately to do: figure out how to deal with blank scan lines. 2016-03-10 22:08:50 -05:00
Thomas Harte
20ac630e4d Some minor optimisations and timing tweaks. Nothing of substance. 2016-03-10 19:58:50 -05:00
Thomas Harte
df3fff51c7 These interrupts apparently last only 64µs at most. 2016-03-10 19:10:53 -05:00
Thomas Harte
f232a12fad Fixed RAM timings: it's at least two and possibly three cycles to access RAM, and an access that overlaps with video fetch in Modes 0–3 will cost the length of the video fetch rather than somehow finishing in time. 2016-03-10 19:04:43 -05:00
Thomas Harte
c7976dd657 Started trying to clean up my Outputs namespace by moving stuff related to the CRT underneath a separate subnamespace. 2016-03-08 20:49:07 -05:00
Thomas Harte
6dfe877c43 Basic attempts to organise myself into shape for composite output continue. 2016-03-07 21:22:47 -05:00
Thomas Harte
1e5fe2b2c1 Made an attempt to reestablish the Atari 2600 output connection despite various changes (TODO: generalise that stuff), and to start creating the composite shader. 2016-03-07 21:04:04 -05:00
Thomas Harte
cd9c62acca Still stepping slowly towards a working composite mode, switched the RGB sampling function to returning a vec4, which may be of benefit to any machine with a brightness part of an RGB signal, and started edging towards at least having the correct GLSL programs ready for converting composite output. 2016-03-07 19:08:26 -05:00
Thomas Harte
3b6c9c15a1 Switching momentarily back to monitor mode, resolved why I was suddenly getting no output upon creating some texture targets. 2016-03-07 18:55:15 -05:00
Thomas Harte
eefd17ed4c Fixed sync response in composite scan output generation and stored texture coordinates. 2016-03-05 21:52:22 -05:00
Thomas Harte
5c8db71c64 Corrected some constants, ensured both machines (so far) are setting the output device. 2016-03-05 16:19:10 -05:00
Thomas Harte
7839d93344 With the provision of an extra hint to the CRT and, finally, the realisation about why my scans weren't exactly joining up, improved output precision. 2016-02-27 22:39:01 -05:00
Thomas Harte
1c6de7692d Made an attempt to fix tape output interrupts; offloaded raster width and placing conversion to the GPU. 2016-02-27 20:37:41 -05:00
Thomas Harte
db18c85423 Simplified the run builder rather; put a double check of Electron timing in place. 2016-02-25 22:01:42 -05:00
Thomas Harte
1eea28b692 Disabled some debugging parts, added some others, marked some things as inline. Ticking over. 2016-02-22 23:35:42 -05:00
Thomas Harte
ec3cccbb0d Working towards HQ UEF support: fixed bug whereby writing to tape output would reset input pulse stepper; added support for chunk 0116 and approximate support for 0113. 2016-02-20 22:03:14 -05:00
Thomas Harte
3754cf4bce Played about with interrupt timing. 2016-02-20 21:24:02 -05:00
Thomas Harte
574985f9a2 Fixed interlaced timing; switched to a more robust detector for horizontal sync; eliminated some test logging. 2016-02-20 20:29:40 -05:00
Thomas Harte
00f414d757 Made an attempt to reintroduce interlacing and screen modes with gaps. Something's wrong with synchronisation though, so most likely I'm outputting a bad signal. 2016-02-20 17:32:51 -05:00
Thomas Harte
da361be3ee This might be more accurate? Probably not. Who knows? 2016-02-20 00:13:43 -05:00
Thomas Harte
518c134348 Blank lines are missing (if the double negative can be forgiven) but the framebuffer is otherwise seemingly working well again. 2016-02-20 00:11:23 -05:00
Thomas Harte
a3432120f3 Fixed synchronisation — my two fields weren't of equal length, I wasn't breaking calls to the CRT upon 40/80 transitions, I had the wrong maximum run length. Now I just need to put real pixels back in. 2016-02-19 23:57:57 -05:00
Thomas Harte
1954f7bcbd Got back to a stable image, at least when staying in a mode. Which is what I was trying to fix. Hmmm. 2016-02-19 23:41:09 -05:00
Thomas Harte
dce1649fc5 Commuted some camelCase variables into more standard C++ underscore names; decided the best fix for the graphics output is to break it down into much simpler chunks. output_pixels is currently a placeholder that simply outputs blank so the current effect is that all data is missing but it should be easy enough now to put pixels back in. 2016-02-18 23:23:49 -05:00
Thomas Harte
0b5417ab44 Made an attempt to put interrupts in the correct places regardless of even/odd field. 2016-02-16 20:36:19 -05:00
Thomas Harte
a01f90ff3e Attempted a switch to the real PAL visible area and to something a bit like a real phosphor decay. 2016-02-14 21:57:23 -05:00
Thomas Harte
7580d192d5 Fixes: now setting correct frame time estimate, properly enabling the timestamp attribute, and ensuring that the Electron flushes screen work at least once per host frame update. 2016-02-14 19:28:02 -05:00
Thomas Harte
7bd237193d Edged closer towards realistic timing. 2016-02-13 20:52:35 -05:00
Thomas Harte
341fafd3c5 Adjusted visible area. 2016-02-12 19:52:04 -05:00
Thomas Harte
1d20a29d97 Made an attempt to switch to the flywheels for both vertical and horizontal sync, and to act more appropriately for out-of-bounds sync requests. Lots of tweaking to do, I fear. 2016-02-11 23:43:08 -05:00
Thomas Harte
86017de1fb Fixed field timing. It's 312.5 lines now, closer to the PAL standard. 2016-02-11 22:12:37 -05:00
